October Big Day—14 Oct 2023

By Team eBird October 10, 2023

Mark your calendars for October Big Day—14 Oct 2023! Like Global Big Day, October Big Day is an opportunity to unite around our shared love of birds. Last October, nearly 35,000 people from 185 countries submitted 80,000 checklists with eBird, demonstrating the power of birds to bring people together.

Wherever you are on 14 October, take a few minutes to join in this global celebration. Participate from anywhere—even from home! By taking part in October Big Day you’re also celebrating Global Bird Weekend and World Migratory Bird Day. Be a part of the global team and help set a new record for October birding.

How to participate

  • Get an eBird account: eBird is a worldwide bird checklist program used by millions of birders. It’s what allows us to compile everyone’s contributions into a single massive October Big Day list—while at the same time gathering data to help scientists better understand birds. Sign up here. It’s 100% free from start to finish.
  • Watch birds on 14 Oct: It’s that simple. You don’t need to be a bird expert or go out all day long, even 10 minutes of birding from home counts. October Big Day runs from midnight to midnight in your local time zone. You can report what you find from anywhere in the world.
  • Enter what you see and hear in eBird: You can enter your observations via our website or download the free eBird Mobile app to make submitting lists even easier. Please enter your checklists no later than 17 Oct to be included in the results announcement.
  • Watch the results roll in: During the day, follow along with bird reports from more than 180 countries in real-time on our October Big Day page.
